Hire me to build your app!

Máté Kovács

iOS Developer in Barcelona


my name is Máté and I am an iOS developer with over 7 years of experience. I am here to make your app stand out from the App Store, and doing it with the highest quality. I do not only know how to build an app, I also know how to make an app to succeed in the App Store. How? I am currently working as an independent developer living off my sales from the App Store.

I started this journey at the beginning of 2017 and in just 6 months I reached the point where my app revenue was enough to cover my living expenses. Since 2017 I released 15 apps on my own and worked some clients projects too. My apps in total got 1,000,000 downloads in just 3 years and this number is increasing day-by-day.

Making a successful app is not only about making a really good looking app. You need to know about App Store search optimization, watch OS development, ideal screenshot, how to increase conversion rates, A-B testing, search ads, analytics and much more. The good thing is that I’m here to help. I did all these things and I know when and which one it the most important to focus on.
